Implementation of non-uniform B-Spline curves according to.
http://en.wikipedia.org/wiki/B-spline
A B-Spline of degree n is defined by at least n+1 control points. Let p be the number of control points, the spline is composed of p-n segments. The knot vector contains m = p+n+1 real values and defines the length of the segments with respect to t. The first and last n values in the knot vector are "extra knots" that specify Bezier end conditions. The remaining p-n+1 knot values define the segment lengths.
The spline is evaluated in a simple manner using the de Boor algorithm. The current implementation is inefficient for large p.
